Lapho ukhetha ama-surfactants okwakhiwa kwakho kokuhlanza noma ukucubungula izinhlelo zokusebenza, igwebu liyisibaluli esibalulekile. Isibonelo, ezinhlelweni zokuhlanza ubuso obuqinile okwenziwa ngesandla—njengemikhiqizo yokunakekela imoto noma ukugeza izitsha ngesandla—amazinga aphezulu egwebu ngokuvamile ayisici esifiselekayo. Lokhu kungenxa yokuthi ukuba khona kwegwebu elizinzile kakhulu kubonisa ukuthi i-surfactant icushiwe futhi yenza umsebenzi wayo wokuhlanza. Ngokuphambene, ezinhlelweni eziningi zokuhlanza nokucubungula izimboni, igwebu lingaphazamisa izenzo ezithile zokuhlanza ngomshini futhi livimbele ukusebenza okuphelele. Kulezi zimo, abaklami badinga ukusebenzisa ama-surfactants anegwebu eliphansi ukuze balethe ukuhlanza okufunayo kuyilapho belawula ukugxiliswa kwegwebu. Lesi sihloko sihlose ukwethula ama-surfactants anegwebu eliphansi, anikeze isiqalo sokukhethwa kwe-surfactant ezinhlelweni zokuhlanza igwebu eliphansi.
Izicelo ze-Low-Foam
Igwebu likhiqizwa ukuyaluza esibonakalayo somoya. Ngakho-ke, izenzo zokuhlanza ezihlanganisa ukuyaluza okukhulu, ukuxutshwa kwe-shear ephezulu, noma ukufuthwa ngomshini ngokuvamile kudinga ama-surfactants anokulawula igwebu okufanele. Izibonelo zifaka: ukuwashwa kwezingxenye, ukuhlanzwa kwe-CIP (indawo ehlanzekile), ukukhuhla phansi ngomshini, ilondolo yemboni neyokuhweba, uketshezi lwensimbi, umshini wokuwasha izitsha, ukuhlanza ukudla nesiphuzo, nokunye.
Ukuhlolwa kwama-Low-Foam Surfactants
Ukukhethwa kwama-surfactants-noma inhlanganisela yama-surfactants-okulawula igwebu kuqala ngokuhlaziya izilinganiso zegwebu. Izilinganiso zegwebu zinikezwa abakhiqizi abasebenza nge-surfactant ezincwadini zabo zomkhiqizo wobuchwepheshe. Ukuze uthole ukulinganisa okuthembekile kwegwebu, amasethi edatha kufanele asekelwe kumazinga aqashelwayo okuhlola amagwebu.
Ukuhlolwa kwegwebu okubili okuvame kakhulu futhi okuthembekile ukuhlolwa kwegwebu le-Ross-Miles kanye nokuhlolwa kwegwebu le-shear eliphezulu.
•Ross-Miles Foam Test , ihlola ukukhiqizwa kwegwebu lokuqala (igwebu elikhanyayo) nokuzinza kwegwebu ngaphansi kokuyaluza okuphansi emanzini. Ukuhlolwa kungase kuhlanganise ukufundwa kwezinga lokuqala legwebu, kulandelwe izinga legwebu ngemva kwemizuzu emi-2. Kungenziwa futhi ezindaweni ezihlukene ze-surfactant (isb, 0.1% kanye no-1%) namazinga e-pH. Abakhiqizi abaningi abafuna ukulawula igwebu eliphansi bagxila esilinganisweni sokuqala segwebu.
•High-Shear Test (bona i-ASTM D3519-88).
Lokhu kuhlolwa kuqhathanisa izilinganiso zegwebu ngaphansi kwezimo ezingcolile nezingangcolisiwe. Ukuhlolwa kwe-high-shear nakho kuqhathanisa ukuphakama kwegwebu lokuqala nokuphakama kwegwebu ngemva kwemizuzu emi-5.
Ngokusekelwe kunoma iyiphi yalezi zindlela zokuhlola ezingenhla, ama-surfactants ambalwa emakethe ahlangabezana nenqubo yezithako ezinegwebu eliphansi. Kodwa-ke, kungakhathalekile ukuthi iyiphi indlela yokuhlola igwebu ekhethiwe, ama-surfactants anegwebu eliphansi kufanele futhi abe nezinye izinto ezibalulekile zomzimba nokusebenza. Ngokuya ngohlelo lokusebenza nendawo yokuhlanza, ezinye izici ezibalulekile zokukhethwa kwe-surfactant zingabandakanya:
•Ukuhlanza ukusebenza
•Izibaluli zemvelo, ezempilo, nokuphepha (EHS).
•Izakhiwo zokukhulula umhlabathi
•Ibanga lokushisa elibanzi (okungukuthi, amanye ama-surfactants anegwebu eliphansi asebenza kuphela emazingeni okushisa aphakeme kakhulu)
•Kulula ukwakheka nokuhambisana nezinye izithako
•Ukuzinza kwe-Peroxide
Kubenzi bamafomula, ukulinganisa lezi zakhiwo nezinga elidingekayo lokulawula igwebu kuhlelo lokusebenza kubalulekile. Ukuze kufinyelelwe le bhalansi, ngokuvamile kudingekile ukuhlanganisa ama-surfactants ahlukene ukuze kubhekwane nezidingo zegwebu nokusebenza komsebenzi—noma ukukhetha ama-surfactants anegwebu eliphansi kuya kwamaphakathi elinomsebenzi obanzi.
